Abstract: Certain implementations of the subject matter can be implemented to screen demulsifiers. A live emulsion of a live hydrocarbon sample and a water sample is flowed through a capillary viscometer. The live hydrocarbon sample includes dissolved gases retrieved from a hydrocarbon-carrying reservoir. While flowing the live emulsion through the capillary viscometer, a demulsifier sample is flowed through the capillary viscometer. The demulsifier sample is capable of causing breakdown of the live emulsion. Using the capillary viscometer, change in a viscosity of the live emulsion over time resulting from the breakdown of the live emulsion due to the demulsifier sample is measured. Multiple images of the breakdown of the live emulsion over time are captured. A strength of the live emulsion is classified based, in part, on the change in the viscosity of the live emulsion over time and on the plurality of images.

Abstract: Fiber-optic equipment is often deployed in various locations, and performance of fiber-optic transmissions may be monitored as a gauge of equipment status to prevent costly and inconvenient communication outages. Events that damage equipment that eventually result in outage and may be desirable to address proactively, but the occurrence of such events may be difficult to detect only through equipment performance. Presented herein are techniques for monitoring and maintaining fiber-optic equipment performance via enclosure sensors that measure physical properties within a fiber-optic equipment enclosure, such as temperature, pressure, light, motion, vibration, and moisture, which are often diagnostic and predictive of causes of eventual communication outages, such as temperature-induced cable loss (TICL), incomplete flash-testing during installation, exposure to hazardous environmental conditions, and tampering.
